1 Claim.

The present invention relates to a wrench having the advantages of thewell known Stillson wrench and providing the advantage of quickadjustability.

The object of the invention resides in the provision of a wrench of thisnature which is exceedingly simple in its construction, inexpensive tomanufacture, easy tomanipulate, thoroughly efiicient and reliable in useand otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention consists in certain novel featuresof construction, and in the combination and arrangement of. parts aswill hereinafter be more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of the wrench embodying the features of myinvention.

Figures 2, 3 and 4 are sectional views taken substantially on the lines22, 33 and 4-4 respectively of Figure 1,

Figure 5 is a sectional view taken substantially on the line 5-5 ofFigure 2.

Figure 6 is a detail elevation of the handle and fixed jaw showing apawl therein.

Figure 7 is a similar view taken at right angles to that shown in Figure6, and

Figure 8 is a perspective view of the casing.

Referring to the drawings in detail it will be seen that numeral 5denotes an elongated handle having a fixed jaw 6 on one end thereof.Numeral 1 denotes the movable jaw from which projects shank 8 one edgeof which is provided with ratchet teeth 9. The adjacent edge of thehandle 5 is provided with a recess l and a pocket H communicating withthe recess. A pawl I2 is pivoted in the recess on a pin I4 and is urgedoutwardly of. the recess by a spring l extending into the pocket ll.Numeral i6 denotes a hollow casing slidable on the shank 8 and is in theform of a U-shaped strap including side plates I1 and I8 and a crossplate I9. Plates I! and [8 have in their upper corners remote from thecross plate [9 registering openings 20, 20 and in the bottom cornersarcuate registering slots 2| and the plate H has intermediate itsopening 20 and slot 2| an arcuate slot 22. The slots 2|, 2| and 22 areconcentrically disposed with respect to the openings 20. The plates I!and I8 straddle the upper portion of the handle and the pin l4 extendsinto the openings 20 so that the casing is rockably mounted. A pin 23extends through the handle into the slots 2| to limit the rockingmovement of the casing. A pin 25 projects from the pawl through theopening 22 so that the pawl may be manually released from the ratchetteeth 9 when it is desired to shift the jaw 'l away from the jaw 6.Suitable indicia may be provided .on one face of the shank 8 so that thejaws may be preadjusted with respect to the pipe before being engagedtherewith.

The recess in is confined between the sides of. the handle. Theconfining sides of the handle provide the support for the pin l4 whichforms the pivot on which both the pawl l2 and the casing l6 rock.

It is thought that the construction, operation, utility and advantagesof this invention will now be quite apparent to those skilled in thisart without a more detailed description thereof.

The present embodiment of the invention has been described inconsiderable detail merely for the purposes of exemplification since inactual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and inthe combination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

A wrench of the Stillson type comprising an elongated handle having afixed jaw thereon and formed with a recess extending inwardly from oneedge and confined between the sides of the handle, said fixed jawfurther formed with a pocket in the inner wall of the recess andregistering therewith, a movable jaw, a shank on the movable jaw formedwith ratchet teeth on the edge confronting the edge of the handlewherein is formed the recess, a pawl rockable in the recess and formedwith teeth on the outer end engageable with teeth on the shank, a springseated in the pocket at one end and bearing on the pawl at the other endto retain teeth on the latter in projected engagement with the teeth onthe shank of the movable jaw, a yoke member embracing the shank on themovable jaw to permit the shank to slide relative to the handle, a pinsupported in the sides of the handle that confines the recess therebyspanning the recess and projecting outwardly on each side of the handle,the pawl rockable on the portion of the pin spanning the recess and theyoke member rockable on the portion of the pin projecting from thehandle,

to the pivot pin, the innermost slot receiving the pin on the pawl tolimit the rocking, movement thereof and the outermost slot receiving thesecond pin to limit the rocking movement of. the

yoke member.
